DISTRIBUTING MANIFOLD FOR- I-IOT-AIR AND VAPOR CABINETS.

Application filed September 1, 1927. Serial No. 216.952.

This invention relates to new and useful improvements 1n distributing manifolds for hot air and vapor cabinets and aids to pro vide a single manifold wherein either hot air or vapor, or both, may be directed therethrough, the primary object of the invention residing in the provision of a manifold of this character that is extremely simple in construction and that may be installed in all characters of cabinets now in use. Furthermore, by reason of the manifold being constructed to permit both hot air and vapor to be injected therethrough the vapor, which is usually of a sulphurous character, is maintained in a warm condition through the entire length of the manifold.

In the drawings wherein there is disclosed two embodiments of the present invention:

Figure 1 is a bottom plan view of a double manifold constructed in accordance with the present invention whereby either hot air or vapor, or both may be distributed thereby.

Figure 2 is a side elevation thereof.

Figure 8 is a detail transverse section taken substantially upon the line 3-3 of Figure 1.

Figure I is a View mainly in top plan and partially in longitudinal section of a single manifold constructed to permit hot air and vapor to be simultaneously passed therethrough, and

Figure 5 is a side elevation thereof.

Now having particular reference to Figures l to 3 inclusive there is disclosed a manifold consisting of a pair of relatively elongated fiat-like pipes 5-5 arranged one upon the other, certain adjacent ends of these pipes converging outwardly as at 6-6, while the opposite ends thereof are provided with T-branches 7-7. Leading into the ends of the outwardly converging portions of these pipes are inlet pipes 8-8, the pipe leading to the uppermost chamber of the manifold having communication with a source of vapor which is usually of sulphurous ch aracter, while the pipe associated with the lowermost chamber is in communication with a source of hot air.

Formed at the side walls of the pipes or chambers 5-5 are diagonally extending branches 9, the end walls of all the branches being provided with exhaust openings, while the side walls of the branches of the uppermost chamber are also provided with exhaust openings as clearly disclosed in Figures 1 and 2. Furthermore the end walls of the T-branches 7'7' are alsoprovided with exhaust openingswhich are preferably of a greater diameter than those of the openlngs 1n the diagonal branches. By reason ofthe branches of the hot air chamber hav-' ing openings in theirend walls only, the hot air cannot readily escape until the same has passed throughout substantially the entire length of its chamber for thus maintaining the uppermost chamber through which the sulphurous vapors pass in a warm condition.

In the form of the invention disclosed in Figures 4 and 5 the manifold consists of a single elongated pipe 5, preferably of circrr lar shape in cross section and constructed at one end with a pair of diverging branches 66' that are open at their outer ends and to which are to be attached vapor and hot air conducting pipes (not shown). The forward end of the single pipe 5 is provided with a T-branch 7, while throughout the length of the pipe 5 are diagonally extending branches 9. The end branch 7 as well as the intermediate branches 9 are formed at their end walls and at theirsides with exhaust openings as clearly disclosed in Figure 5 whereby the hot air and vapor may pass therethrough. In order to prevent the direct contact of the hot air with the sulphurous vapors passing into the pipe 5 there is provided a horizontal bafiie wall 10 located in the end of the pipe 5 formed with the converging branches 6-6, while the bottom wall of the pipe at opposite sides of this wall is formed with exhaust openings as clearly disclosed in Figure l.

It will thus be seen that I have provided two forms of distributing manifolds for hot air and vapor cabinets both of which are well. adapted for all the purposes heretofore designated, even though I have herein shown and described these forms as consisting of certain detail structural elements, it is nevertheless to be understood that some changes may be made therein without affecting the spirit and scope of the appended claims.

Having thus described the invention, what I claim as new is 1. In a distributing manifold for hot air and vapor cabinets, an elongated manifold, said manifold being provided throughout its length with a pair of compartments, lateral branch pipes extending from said compartments, and a pair of branch pipes at one end of the manifold into one of which hot air is delivered to one compartment and into the other vapor to the other compartment.

2. In a distributing manifold for hot air and vapor cabinets, an elongated manifold, means throughout the manifold for providing the manifold into a pair of longitudinally extending separated compartments, and a pair of inlet pipes at one end of the manifold into one of which hot air is delivered to one of said compartments and into the other vapor to the other compartment.

3,, In a distributing manifold for hot air and vapor cabinets, an elongated manifold,

a longitudinal partition through said manifold for dividing the same into a pair of compartments, branches at one end of the manifold into one of Which is to be conducted hot air for delivery into one of said compartments, and into'the other vapor to be delivered into the other compartment and laterally extending perforated branches eX- tending from each of said compartments whereby the hot air and vapor may be exhausted separately.

In testimony whereof I afiix my signature.
